Modeling a DSG for non-electrical purposes using once through boiler for saturated steam (no superheater modules).
I have a system that optimizes steam design parameters ( steam rate, steam temperature etc). Which can be inputted to SAM and estimate potential performance in regards to the solar field steam rate, temperature and efficiencies.
The field is a single loop system with a SM of 0.962, Field thermal output of 7.48005 MWt, Design thermal input power of 7.7778 MWt.
However, I am having issues with the simulation when I make changes to values to mass flow rate and temperature. The simulation seems to run then freezes for certain values of mdot_min and temperature.
Inlet Temp (C) | Outlet Temp (C) | Single Loop Flow Rate (kg/s) | Simulation Process |
50 | 254 | 0.25 | Successful (100%) |
50 | 254 | 2.00 | Freezes/Hangs (12.3%) |
100 | 254 | 2.00 | Successful (100%) |
100 | 254 | 5.00 | Freezes/Hangs (11.3%) |
100 | 310 | 2.00 | Successful (100%) |
100 | 310 | 5.00 | Freezes/Hangs (2.5%) |
Any reason as to what might be the reason or conditions for such response from the simulator.
Thanks
